13.4 AC/DC Parameters
The following tables describe the AD/DC parameters of the PSD4XX family:
J
DC Electrical Specification
J
AC Timing Specification
ZPLD Timing
– Combinatorial Delays
– Synchronous Clock Mode
– Asynchronous Clock Mode
Microcontroller Timing
– Read Timing
– Write Timing
– Peripheral Mode Timing
– Power Down and Reset Timing
Following are some issues concerning the parameters presented:
J
In the DC specification the Supply Current is given for different modes of operation.
Before calculating the total power consumption, determine the percentage of time that
the PSD4XX is in each mode. Also the supply power is considerably different if the
ZPLD_TURBO bit is "OFF" and EPROM_CMISER is "ON".
J
The AC power component gives the ZPLD, EPROM, and SRAM mA/MHz specification.
Figure 38 shows the ZPLD mA/MHz as a function of the number of Product Terms (PT)
used.
J
In the ZPLD timing parameters add the required delay when ZPLD_TURBO is "OFF".
J
In the MCU timing specification add the required time delay when EPROM_CMISER
is "ON".
